What conditions can be confused with eye allergies?
The following is a list of conditions, the symptoms of which are commonly confused with eye allergy.
- Dry eye: This condition results from reduced tear production and is frequently confused with allergy. The main symptoms are usually burning, grittiness, or the sensation of "something in the eye." Dry eye usually occurs in people over 65 years of age and can certainly be worsened by oral antihistamines like diphenhydramine (Benadryl), hydroxyzine (Atarax), Claritin, or Zyrtec, sedatives, and beta-blocker medications.
- Tear-duct obstruction: This is caused by a blockage in the tear passage that extends from the eyes to the nasal cavity. This condition is also typically seen in the elderly. The main complaint is watery eyes that do not itch. Allergy testing will be negative in this case.
- Conjunctivitis due to infection can be caused by either bacteria or viruses. In bacterial infections, the eyes are often "bright red" and the eyelids stick together, especially in the morning. A discolored mucous discharge is often seen, so-called "dirty eyes." Viral conjunctivitis causes slight redness of the eyes and a glassy appearance from tearing. Adenovirus is a major cause of viral conjunctivitis. Herpesviruses, such as the varizella virus that causes chickenpox or shingles, can also affect the eye. Adenovirus infection is very contagious and may be spread by either direct contact, such as hand contact, or in contaminated swimming pools. You should seek medical attention if you suspect any of the above.
